List of Components:

IMD17 - Integrated Motor + Driver
Power Supply (+12 to 24 VDC)
Signal Generator (Pulse or Function Generator)
+5 VDC Power Supply
Voltmeter

Connection Specifications:

1. Begin by connecting your IMD17 to the provided DB9 Cable.

2. If using a function generator, connect the positive end to Pin 9, Step. Connect the negative end of the generator to the negative of your 5 volt power supply.

3. Take the +5 VDC power supply, and connect the positive end to Pin 8, the Opto.

4. Finally, connect your main power supply. Use Pin 1 for the Positive Terminal and use Pin 6 for the Negative Terminal.

5. Touch Pins 2 and 3 with Logic Ground to change the Step Resolution.

6. Refer to the User Manual for Input features.
